things dont always burn up when theyre disabled to my knowledge
or face a certain direction I think that is pretty random as well

could be wrong

Indeed. Could be anything from running out of gas or the tracks getting disloged (all really awful things to happen in a combat situation that'll make the tank a sitting duck) to a hand grenade going off inside and pasting the crew (not sure an anti-personnel hand grenade would set off the tank's ammo)

if it was disabled it would look more burnt out or be facing the other direction.

anyways, I'm just saying the current positioning doesn't really make sense.

If the tank would look more burnt you would be better off calling it a burnt out or overall destroyed tank.

Besides if you study the picture a bit, it shouldn't be too hard to spot the sign which says evacuation outpost. And even the title says the task force is entering a outpost overrun by rebels, as in the rebels managed to take a hold of the camp, probably forcing most of the personnel to abandon vehicles or maybe just killed them all. It's really not that hard to imagine what could have happend.
